A = P(1 + r/k)^(k·t)k = compounds per year, t = years.Frequently asked questions
Does compounding frequency matter much?
It helps, but with diminishing returns. Moving from annual to monthly compounding makes a noticeable difference; monthly to daily is tiny.
What is APY?
Annual Percentage Yield is the effective yearly rate after compounding: APY = (1 + r/k)^k − 1.
